Abstract
Description
Technical Field
[0001] This utility model relates to the field of portable laser cutting machines, specifically to a portable laser cutting machine crossbeam and a portable laser cutting machine. Background Technology
[0002] Laser cutting technology, as a high-precision and high-efficiency processing method, is widely used in metal processing, automotive manufacturing, aerospace, and electronics. The core components of a laser cutting machine include the crossbeam, longitudinal beam, cutting head, laser cutting head, and control system. Among these, the crossbeam, as a key component for support and movement, directly affects the cutting accuracy, speed, stability, and service life of the equipment due to its structural design and material selection. Traditional laser cutting machine crossbeams are mostly made of steel. While steel has high strength and rigidity, its weight is significant, increasing the overall inertia of the equipment and limiting improvements in speed and dynamic response performance.
[0003] In addition, traditional laser cutting machines have the following significant drawbacks:
[0004] 1. Bulky equipment and low relocation efficiency: Traditional beams are mostly made of steel, making them heavy (moving a single piece of equipment requires 3-4 workers and hoisting equipment), and relocation takes 4-6 hours. In special scenarios such as narrow ship cabins and high-altitude platforms, the equipment access rate is less than 40%.
[0005] 2. High maintenance costs and poor environmental adaptability of guide rails: Traditional optical axis guide rails rely on forced lubrication, which can easily leak and contaminate workpieces and equipment. They also require frequent maintenance (an average of 2.4 replacements per year). In addition, construction dust and molten slag from cutting (annual breakage rate exceeding 50%) can intrude into the guide rails, causing slider jamming, loss of precision control, and frequent equipment shutdowns.
[0006] Therefore, there is an urgent need for a portable laser cutting machine. Utility Model Content
[0007] This utility model addresses the technical problems existing in the prior art by providing a portable laser cutting machine crossbeam and a portable laser cutting machine. By designing the crossbeam cross-section structure, it improves assembly efficiency and machine head movement stability, and reduces subsequent maintenance costs.
[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A portable laser cutting machine crossbeam includes a crossbeam, the upper and lower surfaces of the crossbeam are symmetrically provided with optical axis mounting grooves, the opening of the optical axis mounting grooves faces outward, the surface of the crossbeam is provided with a rack mounting surface, and the surface of the crossbeam that is engaged with the rack mounting surface is provided with a cross-shaped groove inward, the cross-shaped groove is composed of mutually perpendicular horizontal grooves and vertical grooves.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Furthermore, the upper surface of the crossbeam is provided with an upward-opening optical axis mounting groove and a rack mounting surface. The rack mounting surface is formed by the side surface of the optical axis mounting groove located on the upper part of the crossbeam and the upper surface of the crossbeam, and has an L-shaped cross section. The cross-shaped groove is located below the rack mounting surface and its opening faces the rack mounting surface. The lower surface of the crossbeam is provided with a downward-opening optical axis mounting groove.
[0011] Furthermore, the main body of the crossbeam is provided with multiple cavities, which penetrate the main body of the crossbeam along its length.
[0012] Furthermore, the crossbeam is integrally extruded and is made of aerospace-grade aluminum alloy.
[0013] Furthermore, a portable laser cutting machine includes the aforementioned crossbeam, two parallel longitudinal beams, with the two ends of the crossbeam respectively connected to the two longitudinal beams, and also includes a machine head, a laser cutting head, and a laser control cabinet; the laser cutting head is provided on the machine head, the machine head includes a gear, a rack is mounted on the rack mounting surface, and the gear and the rack are meshed and connected for transmission.
[0014] Furthermore, the optical axis mounting slot is equipped with an optical axis, and the machine head includes a plurality of V-shaped rollers that cooperate with the optical axis.
[0015] Furthermore, the longitudinal beam is integrally extruded and is made of aerospace aluminum alloy.
[0016] Furthermore, the laser control cabinet and the auxiliary motor are respectively installed at both ends of the crossbeam. The laser control cabinet includes a laser control system, a main motor, and a driver.
[0017] Furthermore, it also includes two parallel connecting rods, and longitudinal beam support frames are installed on the lower surfaces of both ends of the longitudinal beam. The longitudinal beam support frame of one longitudinal beam is connected to the longitudinal beam support frame of the other longitudinal beam through the connecting rods. Leveling feet are installed below the longitudinal beam support frames.
[0018] The beneficial effects of this utility model are:
[0019] 1. The crossbeams and longitudinal beams of this utility model are integrally extruded from aerospace aluminum alloy. The density of aerospace aluminum alloy is only 1 / 3 that of steel. Combined with the cavity weight-reduction design, the overall weight of the machine is greatly reduced, making it easy to carry. The equipment can be disassembled into modular components, and deployment does not require cranes or forklifts, greatly improving relocation efficiency and adapting to narrow spaces and high-altitude operation scenarios.
[0020] 2. The crossbeam of this utility model is made of aluminum alloy, enabling the design of complex cross-section structures through an integrated extrusion molding process. Regarding the cross-section design of the crossbeam, the design of the rack mounting surface and the cross-shaped groove simplifies the rack fixing method and improves assembly efficiency. The crossbeam is equipped with symmetrical upper and lower optical axis mounting slots for mounting optical axes. The optical axes support and guide the movement of the machine head. The symmetrical upper and lower optical axes can support the machine head from both above and below, ensuring that the machine head can move along the predetermined path with high precision and high stability during processing.
[0021] 3. This utility model adopts a combination of an optical shaft mounting groove and a V-shaped roller guiding system, completely eliminating the need for lubrication and preventing oil pollution. Moreover, the sliding fit between the optical shaft and the V-shaped roller has strong environmental adaptability and is not affected by dust or molten slag generated during cutting, greatly reducing the later maintenance costs of the equipment.

The rack mounting surface 3 is formed by the side surface of the optical axis mounting groove 2 located on the upper part of the crossbeam 1 and the upper surface of the crossbeam 1, with an L-shaped cross-section. A cross-shaped groove 5 is formed inwardly on the surface of the crossbeam 1, located below the rack mounting surface 3 and opening towards the rack mounting surface. After the optical axis is inserted into the optical axis mounting groove 2 and the rack is installed on the rack mounting surface 3, a crossbeam 1 assembly is formed, facilitating subsequent use. The length of the crossbeam 1 can be cut as needed. The cross-shaped mounting groove consists of mutually perpendicular horizontal and vertical grooves. The lower surface of the crossbeam 1 has an downward-opening optical axis mounting groove 2. The cross-shaped mounting groove is used to fix the rack, the horizontal groove is used to place the nut, and the vertical groove is used for the bolt.
